Crankshaft Pully Removal

i am trying to remove the bolt holding on the crankshaft pully but i can not get it out. i have even tried using a impact wrench but it still wont budge. if anybody has any ideas on how to get it out i would appreciate it thanks

is the pulley moving while you are trying to unbolt it? if so you need to stick a screwdriver in the flywheel to keep it from turning. if you did that you need a impact wrench with a higher torque capacity and/or more air pressure.

ixnay on the sarcasm, how do u pull of the alternator pulley? I would like to change my crank pulley and alternator pulley. The crank pulley still has the ac and p/s on it. something I would like to change to a single pulley.

is the alternator pulley a press on or screwed on with a nut? the press on needs a puller you can borrow from autozone. for nuts, the easiest way is to get an air ratchet, the kind that doesnt stop when you let off the trigger. set it to tighten, get it going full rpm (after taking it off the car, on a bench), then hit reverse and it will loosen the nut right off. you could also use a corded electric drill the same way.

i finally got the damn thing off i was able to lock the flyweel in place and use a big ass breaker bar, then it was on to changing the timing belt and even more problems. auto tensioners suck, but after a few hours a messing with it i finaly got it on. thanks for the advice on the pully

i do have air tools but my impact wrench was not strong enough to get it out so it was back to the good old big ass breaker bar. i love my impact wrench that was the first thing that it wouldn't take out.
